The area of the base of a cylindrical container is defined by b(x) = x*2 - x + 12. Find

vagabundo [1.1K]

Answer: $V=x^3-2x^2+13x-12$

Step-by-step explanation:

Given

The area of the base is given by $b(x)=x^2-x+12$

The height of the container is $h(x)=x-1$

The volume of the cylindrical container is

$V=Area\times height$

Insert the values

$\Rightarrow V=\left( x^2-x+12\right)\cdot \left(x-1\right)\\\Rightarrow V=x^3-x^2+12x-x^2+x-12\\\Rightarrow V=x^3-2x^2+13x-12$

Simplify the expression -3 ÷ (-2/5

Harlamova29_29 [7]

Answer:

7.5

Step-by-step explanation:

To solve this expression, we can use PEMDAS or order of operations.

Parenthesis

Exponents

Multiplication>Division (Depends on which comes first from left to right)

Addition>Subtraction (See Multiplication>Division)

So First, lets solve the Parenthesis. -2/5=-.4

So now, our equation is -3/-.4

There is no exponents or multiplication, so lets just Divide.

-3/-.4=7.5

The solution is 7.5

Hope this helps!
